BITCH-FILLING TVIACHINE.

Applicationvfiled October 14, 1919.

T 0 all whom it may concern:

Be it known that 1, WILLIAM C. VVrr'r, a citizen of the United States, residing at Alvin, in the county of Brazoria and State of Texas, have invented certain new and useful Improvements in Ditch-Filling Machines, oi which the following is a specification.

This invention relates to new and useful improvements in ditch filling machines.

One object of the invention is to provide a machine of the character described, which has been especially designed for the purpose of filling ditches, which have beenexcavated in the process of laying pipe lines or other under ground conduits. In laying pipe lines or other under ground pipe. a ditch is first excavated and loose earth is thrown up along the side of the ditch and when the pipe is laid in the ditch the loose tlltl'l is then thrown back into the ditch to cover the pipe and to fill the ditch, This is quite a laborious process and the machine herein described has been designed for the purpose of filling said ditch with said loose earth when the pipe has been laid.

Another object of the invention is to provide a machine which is of simple construction, which may be easily operated and which may be cheaply and easily manufactured.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a front elevation of the machine.

Fig. 2, is a plan View thereof, and

Fig. 3, is an enlarged side view.

Referring now more particularly to the drawings. wherein like numerals of reference designate similar parts in each of the figures, the numeral lrei'ers to the land slide, which is formed of angle iron, one wing of which projects down into the ditch 2 and the other wing of which lies flat upon the ground surface adjacent said ditch, as shown in Fig. 1. Spaced from said land slide there is a long mold board 3 which is arcuate in cross section. This mold board converges rearwardly toward the ditch and terminates a distance behind the rear end of the land slide, and its lower edge is formed into a scraper blade 4. The mold board is held Specification of Letters Patent.

Serial No. 330,647.

in fixed relation to the land slide by means of the arcuate braces 5, (l, T, and 8 to whose respective ends the land slide and mold board, respectively. are secured.

At the front and rear ends of the mold board there are the supporting rollers 9 and 10, which are adjustable relative to the mold board and which hold. it at the desired elevation above the ground surface. The roller 9 is rotatably moiimted in the frame 11, which is pivoted on the extended end of the brace 8 and this "frame has the manual lever 12, which is rigid therewith and through which the roller 9, is held at any point of adjustment by means oi the rack and dog arrangement 13. The roller 10 is mountet in a frame 1%, which has the upwardly X tending shank 15 adjustably mounted in the side bearings 16 carried by the outer side of the mold board 3.

In operation, the machine is positioned as shown in Fig. 1, so that the downwardly eX-- tending wing of the land slide will extend down into the ditch and rest against its side. The machine is then pulled along either by teams or by a motor and the scraper blade and mold board will engage against the loose earth at the side of the ditch and gradually force the same toward the ditch and the loose earth will be forced in to said ditch in the rear 01": the land slide, thus filling the ditch and disposing of the loose earth excavated.

The numeral 1? refers to a water tank, which is mounted on the machine and from which the pipe 18 leads forwardly. This pipe is connected to a transverse water pipe 19, one end of which is downwardly turned and discharges water against the side of ditch in front of the land slide, the flow of water being controlled by means of the valve 20. The other end of the pipe 19, is turned rearwardly and extended along the mold board, said extended end being indicated by the numeral 21. This extendedpipe is perforated and discharges water along the mold board, thus keeping said mold board and the scraper blade 42 flushed with water, so as to prevent the earth from adhering thereto, the flow of this water being controlled by the valve 22. r

The front and rear ends of the land slide have small casters as 23, which are provided for the purpose of transporting the machine from one place to another. These casters may be permanently fixed in place or they Patented Aug. 9, 1921 may be made removable so as to be attached only When moving the machine from one piece of Work to another. When it is decided to move the machine from place to place the rollers 9 and 10 are so adjusted as to hold the scraper blade clear of the ground surface.

What I claim is 1. A machine of the character described including a land slide, a scraper blade spaced therefrom and converging rearwardly, relative thereto, cross braces for fixing said land slide and scraper blade in position relative to each other, and supporting rollers for supporting said scraper blade in position relative to ground surface, said supporting rollers being adjustable vertically relative to the scraper blade.

2. A machine of the character described including a land slide, having angularly disposed wings, a mold board spaced from said land slide and fixed in position, relative thereto, said mold board converging rearwardly, relative to the land slide, and having its lower edge formed into a scraper blade, and supporting rollers provided to sustain the mold board adjustable vertically relative thereto.

3. A machine of the character described, including a land slide, a scraper blade, spaced therefrom and converging rearwardly relative thereto, means for securing said land slide and scraper blade in fixed position, relative to each other, and means for discharging Water, against said scraper blade.

4. A machine of the character described, including a land slide, a scraper blade spaced therefrom, and converging rearvvardly rel ative thereto, said land slide and scraper blade being fixed in position, relative to each, and means for discharging Water against said scraper blade, and in front of said land slide.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
